Question
Given two strings s and t, return true if they are equal when both are typed into empty text editors. # means a backspace character.
Example:
- Input:
s = "ab#c",t = "ad#c"→ Output:true - Input:
s = "ab##",t = "c#d#"→ Output:true - Input:
s = "a#c",t = "b"→ Output:false
Candidate's Approach
The candidate used a two-pointer approach to traverse both strings from the end to the start, simulating the backspace operations. They maintained skip counters for each string to handle the # characters and compared valid characters as they moved through the strings.
